Special material requirements of alloy steel flange of Haokun Company
Shanxi Haokun Flange Group Co., Ltd. for the special material alloy steel flange of the current standard of the guarantee conditions of the flange manufacturer according to the current standards of the project inspection and guarantee that the provisions of the standard, said as the guarantee standard material. Assurance conditions are also divided into: special alloy steel flange basic guarantee conditions (also known as the required guarantee conditions). Whether the customer is indicated in the contract. The inspection shall be carried out according to the standard provisions, and to ensure that the inspection results meet the requirements of the standard. Alloy steel special alloy steel flanges, such as chemical composition, mechanical properties, size deviation, surface quality, flaw detection, hydraulic test or flattening or expansion of the process performance experiments, are the required protection conditions. Guarantee conditions of special alloy steel flange agreement: in addition to the basic guarantee conditions, there are still " according to the requirements of the demander, the guarantee conditions of the current standard of special alloy Flange production process characteristics: large flange products are completely made of welding products, no thread. Large flange forging and rolling production process and splicing of three. First cut the plate into appropriate attention, the length of the blade according to the specification of the large flange. Then a ring of ring machine coil, electrode welding interface is the company's joint x-ray spectrum inspection. Then put it with the media, the mud bed processing line and the chamfer, etc., and finally use the dial with the drilling machine in the bolt hole punch processing.12cr1mov special alloy steel flange is used as a pipe for the fluid transport, compared with solid steel such as round steel, in the same bending and torsion strength, light weight, widely used to manufacture structural and mechanical parts, as well as steel scaffolding used in construction. Can improve the material utilization rate of materials, simplify the manufacturing process, save materials and processing hours, is indispensable to all kinds of conventional machinery materials to flange manufacturing.
